Is a block diagram of an installed application installer.

As shown in FIG. 1 and FIG. 2, the application program installation apparatus 100 includes a main control unit 110, an installation processing unit 120, an environment variable setting unit 130, a storage unit 140, and a backup management unit 150. , A system environment controller 160, a compression unit 170, and a decompression unit 180.

The application installation apparatus 100 is installed in the main body of the USB storage device applied as the external removable storage device 101, and as shown in the illustrated external removable storage device 101, various storage devices such as an SD card may be applied. Of course.

When the application program is to be installed in the external removable storage device 101 on which the application installation apparatus 100 is mounted, first, the USB port 202 is applied to the client computer 200 to which the external removable storage device 101 is applied as a client device. And the disk 250 in which the installation target application program is recorded in the disk driver 210 to be installed in the client device 200 so that the client can be installed in the client device 200. It may be installed according to the guide information provided through the guide screen displayed through the display unit 220 of the computer 200.

The main controller 110 provides a menu for adding an application program such as Hangul, a bear player, etc. to the external portable storage device 101 when the application installation apparatus 100 is executed, and the storage unit 140 provides a menu. It provides a menu for guiding the installation of the application and execution of the installed application, such as viewing a list of stored applications, and controls each of the sections described below so that processing corresponding to selection of the provided menu can be performed.

The installation processing unit 120 installs the application program recorded on the installation target disk 250 on the client computer 200 when the application program installation addition on the menu screen provided by the main control unit 110 is selected. Scan the information on the files, the registry, and the services of the client computer 200 before storing them in the prescan database on the client computer 200, and select the client computer (installation of the application program recorded on the disk 250). After the application is installed at 200, information about the files, registry, and services of the client device 200 is scanned and stored in the post scan database on the client computer 200, and then the post scan database and the prescan database are mutually Compare the newly created resources with the create database (create D B) resources created in the prescan database but created later than the prescan time are stored in the change DB, and stored in the create database and the change database. The stored resource is copied and stored in the storage unit 140 of the external portable storage device, and the list of system files, the registry, and services among the copied files is stored in the list DB of the storage unit 140.

In addition, the installation processing unit 120 copies the resource stored in the create database and the resource stored in the change database, and stores the processed data in the external portable storage device 101, and then removes the create database. Similarly, the installation processing unit also deletes the post scan database and the prescan database temporarily created in the client computer 200.

As an example, the system folder of the client device is defined as shown in Table 1 below according to the drive installed by the user.

Removable Disk Folder Alias PC system folder SD_SYSPATH_WINDOWS ("_% _ WINDOWS") Window folder SD_SYSPATH_PROGRAMFILES ("_% _ PROGRAMFILES") Program folder SD_SYSPATH_BACK_SCREEN_USER ("_% _ SCREENUSER") User wallpaper SD_SYSPATH_BACK_SCREEN_ALLUSER ("_% _ SCREENALLUSER") All users wallpaper SD_SYSPATH_START_MENU_USER ("_% _ STARTMENUUSER") User Start Menu SD_SYSPATH_START_MENU_ALLUSER ("_% _ STARTMENUALLUSER") All user start menu SD_SYSPATH_PROGRAMFILE_COMMON ("_% _ PROGRAMFILES_COMMON") Common program file SD_SYSPATH_APPDATA_USER ("_% _ APPDATA_USER") User application data SD_SYSPATH_APPDATA_ALLUSER ("_% _ APPDATA_ALLUSER") All user application data SD_SYSPATHEMP_USER ("_% EMPDATA_USER") User temporary folder SD_SYSPATHEMP_ALL ("_% EMPDATA_ALLUSER") All user temporary folder

Here, in the operation of installing the application program in the external portable storage device 101 by the installation processing unit 120, the following operation proceeds.

First, the data of the registry is changed into an alias according to the location of the system folder of the corresponding client computer PC, and stored in the external removable storage device 101.

Next, the system files copy the data to a folder corresponding to the folder of the external removable storage device 101 based on the system folder data of the client computer 101.

The program file corresponding to the service is changed to data corresponding to the system folder of the client computer 200 and then stored in the external removable storage device 101.

The environment variable setting unit 130 must be stored on the client computer to be executed on any client device connected to the storage unit 140 of the external removable storage device 101, for example, a laptop computer or a notebook computer. A module for setting an environment variable, which is configured to analyze an OS environment of a client device based on a list DB when an application stored in the external portable storage device 101 is selected by an installation processing unit 120 on a connected client device. Set the resources of the application program according to the environment variables of the client device so that the environment variables of the application program suitable for the OS environment are installed on the client device.

The backup manager 150 checks whether there is a system file corresponding to the client and the registry when the application program stored in the external portable storage device 101 is selected by the installation processor 120 on the connected client device. If there is a file and registry but the version is low, it is backed up. When the execution of the application is terminated, the backed up data is restored to a corresponding location of the client device 200.

When the environment variable setting is completed by the environment variable setting unit 130, the system environment control unit 160 skips the reboot of the client device and sends a message indicating that the environment variable has been changed to the client device so that the application can be executed. Passes the process to load the data on the changed registry.

In general, the parts of the registry related to environment variables are loaded only when the client device is rebooted to inform the processes. Therefore, even if the part related to the environment variable is changed while using the client device, the client device does not notify the running process that the registry has been changed and the changed part is not applied. Therefore, rebooting the client device generally needs to be done to apply the changed environment variable of the registry.

Meanwhile, the system environment control unit 160 notifies the process that is running in the program of the client device to avoid such a cumbersome reboot, and informs that the environment variable has been changed. It allows you to see the effect.

In addition, even in the case of a print service among application programs, the system environment controller 160 provides an effect such as rebooting by notifying a running print service to a running process so that the entire running print service can be restarted.

The compression unit 170 supports the compression of an application program stored in the external removable storage device 101 and output to an external device, for example, a client computer or another recording device.

The decompressor 180 supports downloading of the compressed application program from the external device to the external portable storage device 101 and decompresses the downloaded application program.

An application installation process of the application installation apparatus 100 will be described with reference to FIGS. 3 to 9.

When the application program is to be installed in the external removable storage device 101 on which the application installation apparatus 100 is mounted, first, the USB port 202 to the client computer 200 to which the external removable storage device 101 is applied as a client device. ), And install an application target application program, for example, a disk 250 recorded with the following Hangul characters in the disk driver 210 and prepare to install the client computer 200 in an installable manner. In accordance with the guide information provided through the guide screen displayed on the display unit 220 of the client computer 200 by the execution of).

First, as described above, in the main guide screen 410 of FIG. 4 provided by the main controller 100, it is determined whether the software addition menu 401 corresponding to the installation of the application program is selected (step 310).

If it is determined in step 310 that the application is added to the external removable storage device 101 connected to the client computer 200, a guide screen 311 informing notices as shown in FIG. When the menu is clicked, information about a file, a registry, and a service of the client device before the application to be installed on the client computer 200 is scanned and stored in the prescan database (DB), as shown in FIG. 6. A guide screen 412 for guiding the prescan process is displayed (step 320).

After the pre-scan process is completed, as shown in FIG. 7, a window 414 for inputting a name of an application to be installed on the external removable storage device 101 and a path for setting a folder location for the application to be installed as shown in FIG. 7. After setting and setting the name and path through the guide screen 413 providing the input window 415, select the application to install (step 330), as shown in the guide screen 416 illustrated in FIG. The application is installed on the client computer through the program installation process of step 340. The installation process of the client computer 200 of the application program is performed in a conventional manner by a setup file (set.exe) file.

Next, the application determines whether the installation is completed on the client computer 200 (step 350). If it is determined that the application is completed, the application is installed on the client computer 200 and then the file, registry, and services of the client computer 200 are installed. The resource information is scanned and stored in the post scan database (step 360).

After step 360, the guide screen 417 of FIG. 9 is provided to compare the post scan database and the prescan database to store newly created resources in the create database, and the creation time is in the prescan database. Resources created at a later time than the prescan time are stored in the change database (step 370).

Thereafter, the resource stored in the create database and the resource stored in the change database are copied and stored in an external removable storage device (step 380), and the create database is removed (step 390).

In addition, a list of system files, a registry, and a service among the files copied to the external removable storage device 101 is stored and processed in the list DB.

When this process is completed, an installation completion guide screen 318 as shown in FIG. 10 is provided.

On the other hand, when the user wants to execute the application installed in the external removable storage device 101, the user accesses the client device of the target to execute the external removable storage device (101). When the user checks the folder of the external removable storage device 101 and clicks and executes an executable file of an installed application program such as Korean or Word, the environment variable setting unit 130 analyzes the OS environment of the connected client device. Check whether the application is installed on the client device. Installation of such applications can be confirmed by checking registry information of the client device.

On the other hand, if the application is not installed on the client device when the executable file of the application installed in the external removable storage device 101 is clicked, the environment variable setting unit 120 is the OS of the client device among the environment variables stored in the list DB Processes environment variables appropriate for the environment to be installed on the client device.

At this time, since the environment variables provided to the client device are different from the files and locations stored in the client device according to the OS of the client device, the environment variable setting unit 130 resets the appropriate files and locations according to the OS to the client device. Provide for storage.

In more detail, the system files except the program folder are copied to match the system folder of the client device currently connected, among the files stored in the external removable storage device 101. If the data already exists in the folder to be copied, the version of the data is checked and if the version is low, the backup management unit 150 described above backs up to a specific folder and then copies the data of the external removable storage device 101 to the client device. . This is because the backup process uses a file on the client device that is currently connected because the version used by the program you want to run is higher. Therefore, the file applied when the application installed in the external removable storage device 101 is not used is deleted, and an error occurs due to the absence of a file that should exist on the original client device. Deleting a file restores the backed up file to the client device.

In addition, when applying registry data, the data is applied by changing the alias of the registry to match the system folder of the client device. If a key of the registry to be applied already exists, the data is backed up and the registry data of the external removable storage device 101 is applied. The reason for the backup is the same as the reason for backing up system files.

When applying a service, change the location of the executable file among the properties of the service file to match the system folder of the client device before executing the alias. If the applicable service is already running, back up the configuration data of this service and stop and delete the service. Since the service is a running program, simply saving the setting does not apply the new service. Therefore, to apply the service normally, after stopping the service and deleting it, apply the new service. The reason for the backup is the same as the reason for backing up the system file.

Through this process, after the environment variable of the application program is installed on the client device, the application program is executed and the user can use it on the client device.
